Resumen:
10.1039/D1GC02654BThe first perfluoroalkylation reaction of activated arenes (amino-substituted arenes and alkoxyarenes) has been achieved inwater by employing the dyad Rose Bengal and hydrosoluble unmodified vitamin B12 (cyanocobalamin) as photocatalyst andco-catalyst, respectively. The reaction is performed under green LEDs irradiation and employs perfluoroalkyl bromides asperfluoroalkyl radical sources. In particular, the presence of vitamin B12 co-catalyst is found to be fundamental to elicit theformation of perfluoroalkyl radicals.
